No, those who contest jurisdiction and prevail would be dismissed from the case. There would be no further decision on them from this judge.
If some successfully win dismissal, it won't automatically apply to the rest. The judge could rule the same for them, but there's no guarantee. Each defendant has to put on his own defense.
